Reasoning:
- Different Linux DEs specify different titlebar button (min, max,
close) locations which we did not and could not support before.
- Previous approach copied from Firefox depended on custom offsets
specified in CSS instead of allowing the browser engine to place
elements
Changes:
- Titlebar and menubar no longer collapsed into each other with a
negative margin, instead just a single flexbox (on macOS the titlebar
is still collapsed into the tab bar)
- Support for -moz-gtk-csd-reversed-placement to correctly place the
titlebar buttons on Linux
- Removed/changed some code copied from Firefox that does not apply or
uses the wrong selectors
- Fixed the display of Linux Unity DE buttons with icons appearing outside
of button borders
- Removed the Z in the titlebar on Linux since only a few DEs use that.
- Aligned the tabbar on Linux and Windows to the left margin of the
window.
- handle space and enter in zotero pane to always click on toolbarbutton.
It ensures consistent behavior across all components to avoid Enter
triggering click on some buttons but not others.
- address the issue of focus not being able to leave the reader once it
gets there. On Escape, when reader is opened, instead of re-focusing the reader,
focus the selected tab. From there, Enter will focus the reader, and tabbing
allows you to reach the itemPane.
- Tab/Shift-tab moves focus between Sync button and itemPane when
reader is opened
- min/max-lines attribute on editable-text determines how tall the field
can/has to be
- if max-lines is not specified (or is below 1), the textarea will expand
as much as needed without overflow
- removed hardcoded height and variables from css, substituted them with
usage of these attributes for consistency
- No fields have any max-lines at this point, so all fields will expand as
needed
- Added tooltip to display the entire title of the tab on hover
- Ellipsize the text of the tab title to display as much of the last
word as possible
Fixes: #3609
- right/left arrows on section header expand/collapse the sections
- space/enter on section header toggle section collapsed/expanded
- tab from the header goes through the header's buttons and then
tabs into the section if that's opened
- arrow up/down on the header jumps to the previous/next header
- space/enter on clickable elements simulate a click
- if there is a pinned section, tab from the title will focus its header
